ros::init(...) throws an error - Windows roscpp

Question

I'm trying to use ros in cpp with Visual Studio 2012. I wrote the publisher and subscriber tutorial (http://wiki.ros.org/ROS/Tutorials/WritingPublisherSubscriber%28c%2B%2B%29) and first, I configure the project as says in the guide (http://wiki.ros.org/win_ros/hydro/Msvc%20SDK%20Projects).

Then i compiled an linked the publisher, but when I tried to run it, ros::init(argc,argv,"talker") throws an exception... The console says that I ROS_MASTER_URI is not defined but I've got it defined

There are 2 images here: https://www.dropbox.com/s/o12m0l38gaxiugi/error1.png - https://www.dropbox.com/s/ocdmf0wj6rj0962/error.png

Can anyone helps me?

Thanks in advance

So, I had the same issue, although I didn't set the ROS_MASTER_URI globally.

I managed to get around this specific issue by adding

ROS_MASTER_URI=http://localhost:11311

to the debugging environment variables (Project->Properties->Configuration Properties->Debugging->Environment).

However, after implementing the above I got an uncaught exception (Unhandled exception at 0x768bc41f in ros_demo.exe: Microsoft C++ exception: std::bad_alloc at memory location 0x0028f0e4..).

That went away when I built, compiled and ran the project in release mode (which matched my ROS SDK build).

I got the idea for the release/debug build from here:

xstring isn't an OSG specific object, so the error is elsewhere in the 3rd party dependency chain. As I know nothing about your OS and software setup I can't speculate what this might be.

In general though this type of error could well be a linking issue - for instance Visual Studio is hopeless at handling different libs being built debug and release and will crash randomly.

That was fun to discover..
